Abstract: In order to eliminate the defects such as complex mechanism, inaccurate locating, low adaptability and high kernel residue proportion and etc in the existing jujube kernel removing machines, based on the comprehensive analysis of the existing machines and mechanisms, a novel mechanism for jujube kernel removing was proposed in this paper, the feeding mechanism and locating mechanism were designed. Also the key parameters of the main transmission and the executive mechanisms were presented and calculated. Finally, the prototype was manufactured and the experiments were carried out. The results indicated that this machine was suitable for jujube with diameter in the range of 10-24 mm, which had advantages of no sorting, good adaptability and low proportion of kernel residual (less than 2%).
